The purpose of this study is to clarify the physiological and psychological effects of chromatic lighting through the subjective experiments. In this paper, we first compared the psychological effects of various illuminance and chromatic lights and confirmed the main effect of light colour on psychological stress. In the monochromatic lights, the green lights were stressless and the red lights were stressful. Among the mixed lights made of two kinds of monochromatic lights, the yellow lights tended to be stressless. We also examined the additivity of psychological stress from the viewpoint of irradiance. The result shows that the additivity could be assumed among blue, red, and their mixed light magenta at the conditions of 53 lx in front of the eyes, however, the additivity of other mixed colour lights needs to be investigated in the future with more experimental data.

In this paper, we study the [Formula: see text] form-factors with the light-cone QCD sum rules, where the B-meson light-cone distribution amplitudes are used. In calculations, we observe that the line-shapes of the B-meson light-cone distribution amplitude ϕ+(ω) have significant impacts on the values of the form-factors, and expect to obtain severe constraints on the parameters of the B-meson light-cone distribution amplitudes from the experimental data in the future.

Although it would be quite unacceptable to attempt most forms of treatment without defining the dose, acupuncture has so far remained without any means of quantification. Electrical and deep manual needling probably rely for their main effect on direct nerve and muscle stimulation. It is suggested that superficial needling acts by producing a cone of tissue damage, with release of inflammatory mediators which increase the sensitivity of local nerve endings so that trivial, incidental stimulation continues to induce CNS inhibitory effects for a prolonged period. The degree of local inflammatory effect can easily be recorded by measuring the area of skin flare. A simple formula is offered to determine the dose of acupuncture, based on skin flare recordings after experimental needling and theoretical considerations of tissue damage. Needles of varying shaft radius were inserted to a number of depths in the abdominal dermis and subjected to specific degrees of stimulation. The experimental data correlate well with the theoretical model. Needle response increases with depth of insertion, and with needle thickness although this is outweighed by the effects of manipulation if carried out. The formula derived for determining the dose of acupuncture which correlates with inflammatory response, as measured by skin flare, is (r + 0.1 l)K, where r is the radius of the needle shaft, l is the depth of insertion and K is 10 for unmanipulated insertions or 12.4 if the needle is manipulated.

Complete γ-decay in the 12 C (12 C ,γ)24 Mg and 12 C (16 O ,γ)28 Si reactions has been measured at energies close to the Coulomb Barrier using the DRAGON spectrometer and its associated BGO γ-array at the TRIUMF facility. The experimental data show an important feeding of doorway states around 10-11 MeV in both reactions. Comparisons with simulations allow to extract the full capture cross section and the main spin involved in the process. Different models are confronted to the results : completely statistical, semi-statistical with an unique entrance spin and cluster. The resolution of the BGO enables to eliminate a fully statistical scenario but is not enough to disentangle the two remaining scenarii. It is shown that the future PARIS array composed of the recently developed LaBr 3 scintillators will have capabilities to distinguish between these two scenarii.

The theme of designing the future corresponds to the age tasks of older adolescents, but becomes a source of tension in families long before the children finish school. When children reach adolescence, communication is rebuilt in families, and dialogue between children and parents is often difficult. The article discusses the features of what parental statements about the future of adolescents sound in the presentation of adolescents themselves. There are described 20 typical forms of statements about the future faced by modern adolescents from their relatives, that have a different focuses — on the child, on his/her family and on the social environment. Their advantages and disadvantages and possible psychological effects are analyzed; the representation of categories of statements in groups of adolescents of different age and sex and students in different organizations is compared. The necessity of organization of constructive discussions of the future between the teenager and his social environment is proved.

In this paper, we tentatively assign the [Formula: see text] to be the [Formula: see text] type vector tetraquark state and study its two-body strong decays with the QCD sum rules based on solid quark–hadron duality, the predictions for the partial decay widths [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text] and [Formula: see text] can be compared to the experimental data in the future to diagnose the nature of the [Formula: see text].

ABSTRACTThe Schottky barriers that forms on the interface between aluminum and organic semiconductor of polymer heterojunction photodiodes based on poly(3-hexylthiophene): [6,6]-phenyl-C61-butyric acid methylester blend, has been investigated according to Mott-Schottky curves. We focused on the effect of light intensity on the Schottky barrier widths and I-V characteristics of the devices. Comparison of the mathematical models and experimental data measured under different light intensities indicate a dependency of Schottky barrier to the light intensity.

In this paper, we perform an systematic study of the radiative transitions among the bottomonium states using the heavy quarkonium effective Lagrangians, and make predictions for the ratios among the radiative decay widths of a special multiplet to another multiplet. The predictions can be confronted with the experimental data in the future.
